ENGINE SUPPORT AND CRANK CASE.

Application filed. July 25,

To all fio/ofniz't lli-aig/ Conca/Hi Be it known that lf, Pimm. B.Woonnnrr, a citizen of the United States, and a resident of Humeston, inthe county of `Wayne and State of Iowan have invented a certain new anduseful Engine Support and Crank Case, of which the following is aspecilication.

The object of my invention is to provide an engine support and crankcase of very simple, durable a nd inexpensive construction. i

A further object is to provide a device ot' the kind mentioned, havingla portion adapted to be mounted on the main frame of a motor vehiclechassis `and to conveniently support in a rigid manner the motor, and toprovide in connection therewith adetachable member, which serves as acrank transmission and fly-wheel case.

More particularly, it is my object to provide such a device, which soconstructed and arranged as to facilitate access to the parts of theengine for purposes of repair and replacement.

With these and other objects in view, my invention consists in theconstruction, arrangement and combination o'l" the various parts of mydevice whereby the objects contemplated are attained, as hereinaftermore fully set forth, pointed out in my claim, and illustrated in theaccompanyinp, drawings, in which:

Figure 1 shows a side elevation ot an engine support and crank case withan engine or motor mounted thereon.

Figure 2 shows a vertical, transverse, sectional view taken on the line2-2 o1' .Figure l, illustrating the connection between my device and themotor and also the method of hanging my device on the main frame.

Figure 3 is a detail, sectional view taken on the line 3--3 ot' Figure1; and.l

Figure 4 shows a top or plan view of the engine support part of mystructure.

1n the accompanying drawings, I have used the reference numeral 10 toindicate generally the cylinder block of an autoincbile engine` such forinstance as the ordinary Ford engine.

The cylinder block olE an engine of this type is ordinarily mounteddirectly on the crank case and the crank case is mounted on the frame ofthe chassis.

The ordinary crank case has a plate on its under surface, which isremovable to permit access to the connecting rod bearings.

1921. Serial No. 487,533.

The old structure just mentioned has certain serious detects in thatwith such a structure, 1t is very diilicult to ,fret proper access tothe engine parts l'or purposes o1 repair or.

replacement.

iVith the old structure, it is iinlmssible to repair the main hearingswithout entire-ly removing themotor from the car.

ln my device, l. have provided an engine support element, whichcomprises opposite spaced side menibers 11 arranged substantiallyparallel with each other and having; the iorm of outwardly openingchannel bars. At their' forward ends, the members 11 are slightlyinclined toward each other, as at 12, and are connected with a smallcasing 13 for the 'fan pulley. i

The casing 13 supports at its forward end the front engine hanger llt.The hanger 14- projects forwardly from the casing 13, so that it may besupported on the transverse frame memberl 15.` At their rear ends, theframe members 11 are inclined outwardly away from each other, as at 16,thence rearwardly as at 17, thence toward each other as at 18 and thencerearwardly as at 19. The portions 16, 17, 18 and 19 have the channel barshape.

The portions 17 are supported on the main frame members 2O of thechassis by meansof hangers 21. Each hanger 21 may have an outwardly,opening` channel-shaped member 22, having at its Outer upward portion,an upwardly inclined upper member 23 terminating in a lateral extension24, which rests on the `main frame member 2O and is bolted thereto, asat 25. A bolt 26 is eX- tended through the main frame 2O and the hanger21 as shown in Figure 3.

The motor 10 has a flange 26, which sets upon the upper flange of thesupport 11, as shown in Figure 1, and is bolted thereto by bolts 27. Theupper half of the ily-wheel and transmission case 28 has a flange 29,which rests upon the upper flanges of the members 16, 17, 18 and 19, asshown in Figure 1, and is bolted thereto by bolts 30.

I provide in connection with this part just described, a crank case 31having a flywheel portion 32 and a transmission portion 33. The crankcase is provided with a flange 34, which is bolted to the lower flangeof the member 18 by means of bolts 35.

Detachably fastened to the bottom of the crank case 31 is a removableplate 36.

It will be seen that in the practical use of my improved device, theengine is supported on the support Il, and the support 11 is supportedon the main iframe, as shoivn at the lett-hand ot' Figure 1 and inFigure 3.

ln order to give added strength to the support 11, the edges of its`l'lzmges are inclined toward each other, as shown at 37 in Figure Q.

It will be seen that by the construction above described, l haveprovided a strong,` and rigid support 'for the engine and a propersupport for the crank case. The eranh case is so mounted on the support11 that the entire crank case may be readily removed Vor permitting`access to the motor parts, especially the cylinders and connecting rodsand also to the {1y-Wheel and transmission.

It Will be noted that the supjjiort 11, having its members connected asshown and as especially illustrated in Figure l forms av unit, which canbe conveniently packed, transported, installed or disassembled. It is anunit which can be easily and readily mounted on the trame of the car andupon which the engine can be easily and rigidly supported andconnected.y

It may be mentioned that the hand crank extends through the member 14for engagement With the front end of the engine sha-tt.

It should be mentioned perhaps that the easingY 151 which extends belowthe 'fan pulley has at its rear end a partition 4:0, as shownparticularly in F igure 4.

Some changes may be made in the details oit the construction andarrangement of the various parts ot my improved device Without departingfrom the real spirit and purpose of my invention, and it is my intentionto cover by my claim, any modified forms of structure or use ofmechanical equivalents, which maj,v be reasonably included Within itsscope.

l claim as my invention:

ln a device ot' the class described, the eom bination ot' a motor framemember, a supporting device mounted thereon, 'comprising spacedoutwardly opening' channel-shaped njiemb'ers, a easing or receivingelement at the forward ends of said last members, an engine supported onsaid supporting device members, a Hy Wheel. and transmission covercasing,` supported on other parts ot said members, a crank case havingfly Wheel and transmission case portions supported on the lower flangesof said supporting` members, a hanger at one end of said first-namedcasing, spaced hangers secured to said supporting members near the otherends and to the chassis trame members.
